To all whom it may conce-rn Be it known that W'ILLXAM S. Scrmonman, a citizen of the United States, residing in Austin, Chicago, in the county of Cook and State of Illinois, have invented n new' and useful Improvement in Yokes for Draft-Gears, of which the following is o.. specification.

This invention relates in general to yokcs for draft gears and has for its object broadly the provision of a. yoke for a draw bar of new and improved construction and from which the draw bar may be removed from the front and Without requiring the removal of the yoke.

The invention has for its further object #the provision of a yoke for a draft gear of greatly increased strength and ci' simple and economic construction. 1

A still further object; of the invention is the provision of such a structure in which tie draw bar when secured will engage on all four sides.

Another obiecl, o'ihe invertion is die provision of a yoke for a. draw bar so constructed and arranged that the drow liar itself insures against separation of the parts of the yoke.

Other obiects and 'advantages of eiie invention will be apparent as it is betier unfderstood from the following description when considered in connection Witli` Vthe nccompanying drawings illustrating a. preerred embodiment'J thereof.

-Referring: to the drawings,

Figure l is a side elevation of u yoke enlliodving my present invention;

Fig. 2 is a top plan view ot ille seme;

Fig. 3 is e lseotimi aken substantially en ille lines 3 3 of Fig. l;

Fig. 4- is section taken substantially on the lines 4-4 of Fig. 1;

Fig. 5 is a side elevation of o somewhat modified form of my invention;

Fig. 6 is a top plan view of the same;

Fig. 7 is a section ktaken snbstantinlly en the lines -7 of Fig, 5; and

Fig. 8 is a section taken substantially on the lines 8-8 of Fig. 5.

For the purpose of illustraing my invenu tion l have shown on the drawings wo ein v lyodiine'nrs of it, lie first of i-Vliicli their.

Referring; more particularly to Figs. 1 to 4?-, it will lne noted 'that have shown o, draw bnr ll of ordinary construction having the usual coupler l2 und butt The butt. l 13 is provided with 'ille usual transversely exi'ending key oneriiure M.

ln this embodiment, oi the invention ille yoke consists primarily u ,liead 'l5 end n metal strap i6 which the two limbs sind rear o1' iail olI 'elio yoke nud 'which pro vides :for tlie reception of lle iiollc'yf-Fer 'plaies ond springs (noi: shown).
